Scaling Symmetry and Carrollian Gravity
Hamid Afshar, Mehdi Ahmadi-Jahmani
We formulate matter-coupled scaling-Carroll gravity as a gauge theory and develop a conformal construction for generating local Carroll-invariant couplings. The construction relaxe…
Classification of Conformal Carroll Algebras
Hamid Afshar, Xavier Bekaert, Mojtaba Najafizadeh
We classify a one-parameter family, , of conformal extensions of the Carroll algebra in arbitrary dimension with being the anisotropic scaling expon…
The near horizon dynamics in three-dimensional Einstein gravity
Hamid R. Afshar, Narges Aghamir
We study the asymptotic dynamics of 3D gravity with Rindler boundary conditions both in flat and AdS spacetimes. We do this by using the angular quantization and Hamiltonian reduct…
Holography in CGHS supergravity
Hamid Afshar, Narges Aghamir
We study holographic aspects of 2D dilaton-supergravity in flat space-time using gauge theoretic BF formulation. The asymptotic symmetries in Bondi gauge and at finite temperature…
Flat JT Gravity and the BMS-Schwarzian
Hamid Afshar, Blagoje Oblak
We consider Minkowskian Jackiw-Teitelboim (JT) gravity in Bondi gauge at finite temperature, with non-zero vacuum energy. Its asymptotic symmetries span an extension of the warped…
Flat space holography in spin-2 extended dilaton-gravity
Hamid Afshar, Erfan Esmaeili, Hamid Safari
We present an interacting spin-2 gauge theory coupled to the two-dimensional dilaton-gravity in flat spacetime. The asymptotic symmetry group is enhanced to the central extension o…
